"The O'Rourke team was a joy to work with. Sean came out, met us, listened to what we wanted in a deck, and came back with a very competitive estimate. He was happy to make some revisions, and we hired him. His team took care of obtaining permits, removing the old deck, preparing the ground (including a weed barrier), and building the new deck. Sean was easy to communicate with and kept us updated as things went along. We realized we had made an error in what we requested, and he was able to pivot and give us a beautiful deck that we use often. Our deck is the envy of the neighborhood and we love it! Thanks O'Rourke!"

"We had our chimney tuck pointed and a roof put on the house. The old roof wasn’t torn down this it wasn’t in real bad shape and there was only one layer on. The work was all done in one day and everything was cleaned up when they left."

"I had rainwater coming in through a door and window frame. Dario and Juan knew right away that the problem was coming from where my deck meets the siding. They removed deck boards to discover a gap in the siding. Checked for water damage (thankfully no damage). Sealed the gap. I have not had any rainwater issues since. Price was totally reasonable. We discussed other future repairs/projects for my home and I look forward to working with them again."

Deck Maintenance FAQs, answered by experts

Building a deck without a permit could lead to fines for both the homeowner and the contractor. The exact penalties will depend on your state and municipal building laws. You might also be required to remove the deck and apply for a permit before you can build another. While it might be tempting to skip the permit to save a few bucks, it’ll cost you much more if you’re caught.

Most building codes require that spindles or balusters on deck and stair railings be spaced no more than four inches apart. This safety standard, often called the '4-inch sphere rule,' is designed to prevent small children or pets from slipping through the railing. A good way to visualize this is that a 4-inch sphere should not be able to pass between two spindles. For the same safety reason, the space between the bottom rail and the deck floor should also be no more than four inches. As a general guideline, professionals often install three balusters per foot of railing. However, since specific requirements can vary by location, it is crucial to check your local building codes to ensure compliance before starting your project.

Some elevated decks require stairs that lead to the ground level per the local fire codes in some municipalities. In other regions, a staircase is an optional feature that can increase accessibility and convenience for homeowners who want ground-level access to their deck. Additionally, a staircase is necessary if your home doesn't have an existing door leading to the deck.

You can build an outdoor kitchen on a deck, but you should choose composite decking since it's more heat-resistant. Metal deck materials like steel and aluminum are also good choices because they're less flammable than wood. You should also consider the weight of the kitchen—make sure your deck can support it and any appliances you plan to use. You should consult a structural engineer to confirm exactly how much weight your deck can safely support when building an outdoor kitchen. 

Deck skirting shouldn’t touch the ground, especially if you have a wood deck, which is vulnerable to moisture. Ideally, you should leave at least 3/4 of an inch of space between the deck skirting and the ground for more ventilation. Pros also recommend that you incorporate about 1 square foot of space for ventilation for the underside of the deck to every 150 square feet of decking. Proper ventilation prevents mold growth and rot that can damage your deck.
